Qurinvention relates to electrically dri'ven locomotlves, and it has forits object to so construct and arrange the parts of locomo- ..-tive orother vehicle trucks and the suspen- ,-sion means for the pro ellingmotors as to (render the same more e ective and satisfacchangingconnections, such as, gearing, he

tory in operative service than other struc tures heretofore employed. 1

:In vehi les that areprovided with speedtween the ro elling motors andthexdriving mounted that their armature shafts and the axles, are 'in'substantially 'the' same horizontal plane and, in such cases, themoaxles or w ee s, the motors are usually so tors are supported at one.sidefby means of bea s-upon-the driving axles, and at the other SldG' bysuitable resilient means; However, when locomotives are'equipped withtrains, the motors. are so arge and heavy that.

motors having suflicient, ower to haulheavy -manner above mentionedwithout unduly extending the wheel bases and enlarging the drivingaxle'bearings of the motors. I It is generally desirablethat a verypower- "ful motor shall be resiliently connected to the .driving axle inorder to lessen the severity of 1 the shocks to which the parts aresubjected in service, and a suitable means for this purpose "comprises aquill loosely surroundlng the drivmg axle and having radial arms orflanges from which bosses project into 'cor responding chambers in thedriving wheels, the bosses being surrounded within the I chambers byresilient means, such as the s rings that'constitute the subject-matterof,

-In the structure just specified, the motor is provided with supportingbearingsupon thequill, instead. of upon the aXle,-.and may beoperativelyconnected to the quill by means 0 gears; The-driving springsare, therefore not only subjected to the strains resulting from thetorque of -themotor, but. they: also Specification oi Letters Patent.Application filed January 5; 1907.

- A truck frame 28 for thevehicle is also re siliently-"supported uponthe main journals, but independently of the'motor, by means of leafsprings 29, that are also seat'ed at their e points upon the upports 26and the extremities offwhich areconnectedto the I "truck frame by means.of links 30 and 31'.

Thelower ends ofthe links 30 are connected *directly to"the' mainp.ortion of the truck framewhilethe links 31,- which are longer;

than the links 30, are connected, at weir lower ends, to bars 32thatare' pivotally con- 'nected, attheir middle points, to the mainportion of the truck frame, the o posite ends of thebars 32 beingconnected, y. means of links 33, similar to the links 31, to the ends ofleaf springs. 34 that are'similar in "structure and functlon to thesprings 29 While thus far, the description has pertained only to a'singleflmotor and its mounting, it will, of

course, be understood that vehicles will usually be provided with aplurality of similarly mounted motors, as indicated in Fig. 1, and thatthe motors may be connected together and to a relativel fixed part; suchas the cab. or body of the ve icle', (not shown) by means of links 36and 37.

Since the motors are not, m'the present instance, located between thedriving axles, they do not interfere with placing the axles asnear-together as may be otherwise convenient or desirable and,consequently, they do not enter seriously into consideration whiledetermining the wheel base of-a vehi' cle, and there is less restrictionupon the size of. the motors. .The motors are also resiliently supportedentirely independent of thetruck-frame, andvthe driving springs 9mayberelieved of the greater-portions-of the.

weights ofthe motors and be subjected only to the strains resulting iromthe torques of the motors, or they ma be caused to carry any desiredportions .0 the motor weights.

The bearings 11 and 120f each motor upon the quill may also of'smallerdimensions :and simpler in construction than would be necessary if theywere required to support through the geari is directed along a linemaking an angle 0 approximately-15 {die usual angle, of obliquity ofgears). above the horizontal, the vertical component; of this the entireweight of' the motort Since the reaction of the'torque ofthemotor-exerted reaction will exert a lifting moment upon the motor-andconsequently relieve the '5 rings 180i a corresponding'amount of weig tfor both directions of rotation of the motor. As the motors have beenmounted, heretofore, the reaction of the torque of the motor exerts alifting moment upon the motor for only one direction of rotation, thereaction being add ings and-other parts thereof more readily acce'ss'ible for inspection and attendance, and

it removes them further from the dirt andslush alongthe roadbedthanwould other wise be the case.
